- No escape Tower ... my design adopts MY "underside-LAS" but it can use the (heavier) tower-LAS

- Asymetric lift ... no, the two engines don't burn at lift-off but at 60+ km. (like every multi-engines rocket)

- Severe mission failure in the case of an engine out ... there are many rockets that have two or more engines, the risks of my design can't be higher, however, I prefer/suggest a single "J-2Y superengine" (see the link in my article) atop a 4-segments SRB

- Lower in-atmosphere staging ... if you refer to the rockets' aerodynamics, it can't be worse than other large rockets (DIVH, Ariane5, etc.)

- Still has an enormous literal powder keg underneath a crew ... the "power" under the crew is similar to the Ares-1, the CLV and much less than Shuttle

- Still uses flight of the Phoenix style scavenging ... that's true, it was a critics to the entire ESAS plan, and my design just starts from the reality of facts
